Thread: tunnel ram question

there is no true way to give a carb size recomendation without having the cam specs and compression ratio and also, if running a manual or automatic, the torque converter specs, with rear end gear ratio. you will have to build that 283 pretty stout to get a 2x4 bbl set up to run without a lot of tuning issues, but it can and has been done by alot of people. so dont rule it out if that is what you want. pictured is a basic holley carb size chart, i personally think this chart is a little undersized, but it is always better in being low than high in carb selection.
